I'm close to finishing the Aalto 1.3 upgrade. I had a request for a sneak peek, so here you go. The 1.3 version leaves the sound engine exactly the same, but adds a few of the MIDI and usability features most requested by users. Mostly people complained that Aalto's UI was just too big overall. So I hope you enjoy the new, smaller version:

Cute little guy, ain't he. Wait, what? You said it was too small already? OK, enjoy the new, bigger version:

And yes, you can smoothly resize between the two.

If you look closely, you can see evidence of new capabilities that will be coming. The list is not set in stone and will include some things depending on whether I have time to finish in the next couple of weeks. So I'll hold off on announcing new features until the release is out.

nice! new bits i see:
a random button for the seq, and inlets for lfo's volume and env2's delay & attack (translucent?). also noticed that the 4-voice indicator is gone. is this because of soundplane integration? anyway looking fwd to it! cheers for the peek :)

re: AAX, like RTAS, I'm not sure the number of people who want synths for that platform is not sufficient to pay for the time I would spend writing and supporting it. After 1.3 is out I'll take a look at the new SDK.
